THOMAS A. NAYLOR, OF BALTIMORE, MARYLAND.

CONVEYER FOR COAL-CARTS.

SPECIFICATION forming part of Letters Patent No. 314,869. dated March31,- 1885.

Application filed January 19, 1985. (X0 model.)

To all whom, it may concern.-

Be it known that I, THOMAS A. NAYLOR, of Baltimore city, State ofMaryland, haveinvented certain new and useful Improvements in Conveyersfor Goal-Carts, of which the following is a specification, referencebeing had to the accompanying drawings, forming part hereof, in which-Figure 1 is a top plan view with the body of the cart removed. Fig. 2 isa rear end view, and Fig. 3 is a side elevation, of the conveyer. Fig. 4is a side elevation of my device with the body of the cart thereon, andFig. 5 is an end view of Fig. 4.

Like letters of reference mark similar parts in all figures.

My invention relates to an improved coalconveyer for carts,dumping-wagons, 817C.

The object of my improvement is to facilitate the placing of coal intocellars, and to overcome the difficulties heretofore experienced inelevating the body of the cart with the full load of coal therein, myinvention obviating entirely the raising of the cart; and it consists inthe peculiar construction, arrangement, and combination of parts, aswill be hereinafter explained.

Referring to the drawings by letter, A is the frame; A, a stationary rodrunning from front to rear. A is a square rod, also running parallelwith rod A, both being journaled in the front and rear ends of the cart.Rod A has near its rear end and on the inside of the frame A agear-wheel, B, rigidly affixed thereto, gearing into still anothergearwheel, B, on the end of ashaft, Bflwhich extends through twosupports,b b, the said shaft extending through the side of frame A, uponthe end of which is a crank, b.

O is a cross-beam through which rods A A pass, the square rod Arevolving in its respective ends of said cross-beam O by means of aspool (not shown) revolving in cylindrical holes cut therein, the saidspools having a square hole cut therein to admit of the square rod Aresting firmly therein.

0 is a gear-wheel with a square hole in its center, through which thesquare rod A passes, and by which the said gear-wheel U is revolved.

C is still another gear-wheel, gearing into gear-wheel C, from which itreceives its m0- mentum. This gear-wheel G has also a square hole in itscenter through which passes the square end of rod 0 from which itreceives its rotating power. The outer end of rod 0 is loosely journaledin the outside of slot c,cut in the cross-bealnC, while the otherportion passes loosely through a hole cut in the inside of cross-beam Oas well as a hole in the brace 0. Rod (3 has at its inner end asemicircular opening into which loosely fits the head of another rod,D,rigidly pinned therein by any well-known means, preferably the oneshown.

Around rod D is rigidly aflixed a wormscrew, D, which rests in asemicircular bedplate, D On the outer end of rod D is ailixed anextension, d, for purposes hereinafter explained. The semicircularbed-plate D is rigidly affixed to the under side of cross-beam G at oneend, while the outer end passes through proper slides affixed rigidly tothe under side of the frame A at its rear end; or it may be arranged byresting in a skeleton frame, E, as seen in Fig. 2, or in any well knownmanner, without departing from the spirit of my invention.

The operation of my device may be described as follows: The cart-bodyhaving a central sliding board or any other well-known means to let thecoal fall through its center into the conveyer, and being placed uponthe frame A, and itbeing desired to unload the coal, the conveyer isslid along upon rods A A until it reaches the cellardoor. The opening inthe cart-floor above referredto is then opened, when the coal will ofitself fall through into the conveyer D, lying underneath thereof, whenthe crank bis revolved by the operator, which causes the gear-wheels B Bto revolve, thereby revolving the square rod Aflwhich in turn revolvesgear-wheel G, which also revolves gear-wheel G which revolves the rod 0thereby causing the rod D with its wormscrew D to revolve rapidly, sothat the coal, falling into the conveyer D", is ejected from theconveyer with such great velocity that the time occupied in unloadingthe cart is not to be at all compared with the time consumed in hoistingthe body of carts whose bodies have to be first raised and the coal thendumped into the chute.

When it is desired to reach a cellar at a dis- 2. In combination with acart or wagon body, the worm-screw working within the trough by means ofthe universal joint, the I 5 whole attached to the under side thereof,as herein shown and described, substantially in the manner as and forthe purposes set forth.
